Definitions

  • Alkylpolyglycosides have been prepared by a variety of methods in laboratory, semi-commercial and large scale commercial process techniques. Primary commercial emphasis has focussed on the preparation of C 8 -C 18 glucosides by the reaction of a suitable C 8 -C 18 alcohol or available mixtures thereof with a saccharide reactant (e.g., a monosaccharide or a material hydrolyzable to a monosaccharide) at an elevated temperature in the presence of a suitable acid catalyst.
  • a saccharide reactant e.g., a monosaccharide or a material hydrolyzable to a monosaccharide
  • the resulting reaction product mixture as initially made typically contains a substantial quantity of residual unreacted long chain alcohol, the monoglycoside of the long chain alcohol as the predominant glycoside molecular species on a mole percentage basis, the various higher degree of polymerization long chain alcohol polyglycoside species in progressively decreasing mole percentage amounts or proportions principally from the DP2 through DP10 glycosides.
  • Especially important binary alcohol mixtures include the C 8 -C 10 , C 10 -C 12 , C 12 -C 14 , and C 16 -C 18 where the alkyl groups are derived from naturally occurring fats and oils.
  • Important ternary mixtures include the C 12 -C 14 -C 16 or C 10 -C 12 -C 14 alcohols.
  • the oxo alcohol technology is also employed which provides mixtures containing an odd number of carbon atoms in the alkyl chain, for example an oxo alcohol composed of a mixture of C 9 , C 10 and C 11 alcohols or C 12 and C 13 as well.
  • Other synthetic alcohols may be provided by Ziegler Chemistry in which ethylene is added to a triethylaluminum, which is then oxidized to an alkoxide, which is subsequently converted to a mixture of linear alcohols.
  • alkylpolyglycoside products Since the practice of commercial scale processes for the production of alkylpolyglycoside products is governed chiefly by economic factors, it is not economically feasible to produce a wide variety of alkylpolyglycoside products for distribution in commerce.
  • One important factor in the process economics is the need to employ and recycle excess alcohol in the reactor. This is unfortunate since the applications or end use of these compositions is highly dependent on combinations of factors including carbon chain length, degree of polymerization, and additional factors such as the co-presence of impurities or minor amounts of residual surfactants.
  • a wide variety of applications of alkylpolyglycoside products is known in the prior art.
  • German Application DE-A-4 005 958 directed to liquid, foaming, cleaning agents, more specifically dishwashing detergents, an approach is taken whereby the mean degree of glycosidation (glycoside units per fatty alcohol residue) is not too high.
  • the degree of glycosidation is controlled or determined by mixing two different alkylglycosides of differing alkyl lengths and differing degrees of glycosidation, in which each alkylpolyglycoside has an alkyl group of only one chain length, i.e. all C 10 and all C 11 , or two different alkylpolyglycosides of mixed alkyl groups, i.e.
  • C 8-10 and C 11-18 in which 1-10 parts of the C 11-18 is mixed with 1 part of C 8-10 .
  • Japanese Patent Application JP-A- 63-298821 filed 25 November 1988 and laid open June 5, 1990 (Kokai No. 145696/90) describes a higher alkylglycoside composition said to possess foaming characteristics equivalent to general purpose anionic surfactants, such as sodium dodecylbenzene sulfonate and sodium polyoxyethylene (3EO) dodecyl sulfate.
  • general purpose anionic surfactants such as sodium dodecylbenzene sulfonate and sodium polyoxyethylene (3EO) dodecyl sulfate.
  • compositions comprising 28-92% by weight of (A) with the remainder being alkylglycosides having non-essential alkyl glycosides having alkyl groups of 11-14 and higher. Described are:
  • EP-A-92355 published October 26, 1983, describes the preparation of fatty glycoside mixtures by reaction of a saccharide-containing composition of the formula A-O-(G) x , where A is hydrogen or an organo group of less than 8 carbon atoms, G is a saccharide and x is an integer of at least 1, with a lipophilic alcohol having at least 8 carbon atoms and a surfactant additive of the formula R f O(G) n , where R f is a lipophilic organo group having at least 8 carbon atoms, G is a saccharide unit and n is an integer of at least 1.
  • the reaction may be controlled to promote fatty glycoside mixtures of varying degrees of glycosidation.
  • the mixture may be fractionated into divergent fatty glycoside fractions of differing HLB values, which may be recombined to make a fatty glycoside mixture of predetermined HLB values. No specific example of such a mixture is given.
  • This approach, using individual divergent fractions, is similar to the Japanese approach of combining glycosides of individual, single, alkyl groups.
  • an alkylpolyglycoside composition having a preselected or predetermined average alkyl chain length and surfactant properties can be prepared from the at least binary mixture alkylpolyglycoside compositions prepared commercially as described above. After selecting the predetermined average carbon chain length of the alkyl moiety, the composition having the desired detergent or surfactant properties is prepared by mixing two or more of at least binary components, each binary component having an average alkyl chain length such that when mixed the amounts of the binary components are effective to provide the predetermined selected average alkyl moiety and the surfactant properties.
  • At least binary component as the term is employed herein is meant to include compositions having at least two different alkyl chain length polyglycosides, and accordingly includes ternary mixtures containing three different alkyl chain length polyglycosides.
  • the present invention relates to a method of preparing an alkylpolyglycoside surfactant composition in which the alkyl groups contain from 6 to 20 carbon atoms comprising selecting a predetermined average carbon chain length of the alkyl moiety for the composition and mixing two or more of at least binary components of alkylpolyglycosides, each binary component having an average alkyl chain length such that when mixed, the amounts of the binary components mixed are effective to provide the predetermined selected average alkyl moiety and the surfactant properties and wherein at least one, or both binary components, comprise a Flory distribution of polyglycosides derived from an acid-catalyzed reaction of an alcohol containing 6-20 carbon atoms and a suitable saccharide from which excess alcohol has been separated, characterized in that the predetermined average alkyl moiety chain length is in the range of 9 to 14 and one of the binary components has an average alkyl chain length less than the predetermined selected average alkyl moiety and another binary component has an average alkyl having al
  • the present invention further relates to an alkylpolyglycoside surfactant composition in which the alkyl moiety contains from 6 to 18 carbon atoms and in which the average carbon chain length of the composition is from 9 to 14 comprising a mixture of two or more of at least binary components of alkylpolyglycosides in which one of the binary components has a lower average chain length than the other binary components, and wherein the binary component having the lower average chain length and each other binary component is present in the mixture in relation to its average carbon chain length in an amount effective to provide the surfactant composition with the average carbon chain length of 9 to 14 and an HLB in the range of 10 to 16, and wherein at least one or all of the binary components comprise a Flory distribution of polyglycosides derived from an acid-catalyzed reaction of an alcohol containing 6-20 carbon atoms and a suitable saccharide from which excess alcohol has been separated, characterized in that in the mixture the binary component having the lower average chain length is present in a weight ratio to the other binary components in the
  • the present invention affords a unique and surprising approach to preparing alkylpolyglycoside compositions having a designated average alkyl chain length, which chain length has a predominant impact on HLB and other properties.
  • the composition retains the beneficial effects of each of the binary components while providing the desired HLB and surfactant properties.
  • This approach is in contrast to the approach of the Japanese reference employing pure, single or individual alkylglycosides with the deficiencies attendant thereto.
  • the present invention further affords the advantageous opportunity to utilize the commercial binary or ternary product mixtures prepared from the myriad of alcohols commercially available either derived from natural resources, fats and oils which are preferred from an environmental viewpoint being a renewable source of raw material; or derived "synthetically" through conversion of petrochemical sources such as in the Ziegler process or oxo process.
  • the starting products for preparing the mixtures of the alkylpolyglycoside compositions of the present invention are those described in the related art section above, in which the initial reaction product of the alcohol and saccharide in the presence of an acid catalyst results in a mixture of a monoglycoside of the alcohol and various higher degrees of polymerization (DP) polyglycosides in progressively decreasing amounts, i.e., the diglycoside (DP2), the triglycoside (DP3) and the higher polyglycosides (DP4 and higher).
  • DP2 diglycoside
  • DP3 triglycoside
  • DP4 and higher higher polyglycosides
  • the overall distribution curve seen in Figure 1 is the same, though the average DP of the reaction mixture may vary due to the differing distribution of the various fractions DP1, DP2, DP3 and higher fractions.
  • the Flory distribution of the reaction product after removal of the excess alcohol will have an average degree of polymerization above 1.2, i.e., typically 1.4, with a monoglucoside content in the range of 50-70% by weight of the glycoside product, up to 2.8, preferably up to 2.0.
  • the glycoside products of the reaction of an alcohol and saccharide may be represented by the formula ROG x wherein R is a residue of an alcohol, O is oxygen, G is a glycoside residue, and x is the average degree of polymerization (DP) resulting from the various mono, di-, tri- and higher glycoside fractions present in the product and is a number of 1 to 3.
  • the average degree of polymerization is thus defined as the ratio of saccharide rings to the R groups in the alkyl glycoside.
  • the monoglycoside fraction would have one saccharide ring, the diglycoside would have 2, the triglycoside would have 3 with the higher glycoside having corresponding more rings, the average of which in the product therefore being typically greater than 1, generally in the order of 1.2 to 2.8, with preferred mixtures at 1.4 to 2.5.
  • the alkylpolyglycoside products represented by the formula above contain a lipophilic group, the R group, and a hydrophilic group, the OG x group.
  • the product should have a hydrophilic-lipophilic balance (HLB) of from 10 to 16, and preferably 11 to 14.

  • the present invention provides a method of preparing alkylpolyglycoside compositions having the most desirable HLB for detergent-surfactant use applications with the R group having a preselected average carbon chain length obtained by mixing alkylpolyglycosides as described above.
  • the lipophilic R groups in the alkylpolyglycosides are accordingly derived from alcohols.
  • the groups are derived from the fatty alcohols derived from naturally occuring fat and oils, i.e, octyl, decyl, dodecyl, tetradecyl and hexadecyl.

  • the alkyl glycoside compositions of this invention are prepared by mixing two or more of at least binary components containing alkylpolyglycosides of varying alkyl chain lengths in amounts to provide surfactant properties of a preselected average alkyl chain length.
